Hello tutors,
This is something I've been trying to figure out for some time. Is
there a way in Python to take a string [say something from a
raw_input] and make that string a variable name? I want to to this so
that I can create class instances on-the-fly, using a user-entered
string as the instance name. I can do it with an "exec" statement,
but that would force me to use more "execs" to reference the newly
created class instance[s] and I would rather not do that. I'm sure I
could accomplish something similar using a plain old dictionary, but I
was playing around with the OOP stuff and thought it might be a neat
thing to try out.
I've attached the small function I've come up with to the end of this
message. This is just a model I created for testing purposes, so it's
not the most elegant code. Any suggestions would be greatly
appreciated.
TIA,
tony giunta
def generateInstance():
class test:
def __init__(self, title, price):
self.title = title
self.price = price
def theTitle(self, title):
return self.title
def thePrice(self, price):
return self.price
myName = raw_input("Name: ")
myTitle = raw_input("Title: ")
myPrice = raw_input("Price: ")
exec '%s = test("%s", %s)' % (myName, myTitle, myPrice)
